Does the 120 volt circuit need its own breaker in the pump house?

In a word, yes.
120 volt lighting typically is #14 AWG and requires a 15 amp breaker.
120 volt outlets should be #12 AWG and require a 20 amp breaker.
A simple sub-panel in the well house with a "quad" breaker would be
the simplest solution.

Thanks. I had never seen or even heard of a quad breaker.
